TECHNICAL FIELD

The present invention relates generally to soft tissue repair sites.More particularly, the present invention relates to devices, systems,and methods for repairing soft tissue and attaching soft tissue to bone.

BACKGROUND

One of the most common needs in orthopedic surgery is the fixation ofsoft tissue, such as ligament or tendon, to bone. Typically, fixatingsoft tissue to bone is implemented with a bone anchor and suturematerial with suture coupled between the soft tissue and the bone anchorsuch that the soft tissue is cinched in against the bone. However,coupling suture to soft tissue is time consuming and often requirescomplex suture patterns for effective fixation, often requiringspecialized surgeons. While this can provide a good initial repair, thestrength and quality of the repair may quickly degrade with subsequentloading and mobilization, often resulting is subsequent proceduresdepending on the activity level of the patient. As such, it would beadvantageous to eliminate the complexity and the time consuming natureof this type of surgery while also increasing the long termeffectiveness of the procedure.

DETAILED DESCRIPTION OF THE INVENTION

Various embodiments are disclosed herein of a soft tissue repair deviceand system. Such repair device and system may be sized and configured toapproximate and fuse, for example, soft tissue to bone. The variousembodiments may provide structure that maintains the soft tissue againstbone in an abutting relationship, without gapping. In this manner, therepair device and system of the present invention may provide the properhealing required for fusing the soft tissue to bone.

With reference to FIG. 1, one embodiment of a medical device system 10,shown in an exploded state, is provided. Such medical device system 10may be employed to fixate soft tissue, such as tendon and ligament, tobone. The medical device system 10 may include a delivery instrument 12and a repair device system 14, the delivery instrument 12 designed tofacilitate anchoring a repair device or repair device system 14 to softtissue and to bone. The repair device system 14 may include a softtissue anchor 16 configured to be associated with or coupled to a boneanchor 18. In one embodiment, the soft tissue anchor 16 may be coupledto the bone anchor 18 with one or more flexible members 20. Uponassembling the medical device system 10, the repair device system 14 maybe sized and configured to fixate soft tissue to bone such that, as thebone anchor 18 is being seated and anchored into bone, the soft tissueanchor 16 may be simultaneously seated and anchored to soft tissue (seeFIGS. 5-6).

Now with reference to FIGS. 2 and 2A, the soft tissue anchor 16 will nowbe described. As set forth, the soft tissue anchor 16 may be sized andconfigured to sink into soft tissue and be coupled thereto. The softtissue anchor 16 may include a base 22 and multiple legs 24 extendingfrom the base 22. The soft tissue anchor 16 may be formed from sheetmaterial so that the anchor 16, including the base 22 and the multiplelegs 24, may be formed as a seamless, monolithic and one-piecestructure, as depicted in FIG. 2A. The soft tissue anchor 16 may beformed from a metallic material, such as stainless steel, titanium, orNitinol, or any other suitable medical grade material or combinations ofmaterials. Such metallic material may be laser cut from the sheetmaterial or cut using any suitable technique known in the art. Inanother embodiment, the soft tissue anchor 16 may be formed from apolymeric material or a bioresorbable material. Upon being cut from thesheet material, the legs may be bent to position the legs downward ormoved to orient the legs to extend away from a single side or undersideof the anchor 16, as depicted in FIG. 2. Once the legs 30 have beenappropriately oriented and bent into position, the anchor may then beelectro polished or chemically polished, as desired. In anotherembodiment, the soft tissue anchor 16 may be formed from a medical gradepolymeric material, as known to one of ordinary skill in the art. Inanother embodiment, the soft tissue anchor 16 may be formed from abioresorbable material, as known to one of ordinary skill in the art. Inanother embodiment, as depicted in FIG. 2B, a soft tissue anchor 26 mayinclude a base 28 with legs 30 extending therefrom such that the legs 30may be formed with a barb 32 or multiple barbs extending therefrom. Suchsoft tissue anchor 26 may be formed in a similar manner as the softtissue anchor described and depicted relative to FIGS. 2 and 2A hereinand may be employed with the medical device system 10 (FIG. 1) asdescribed and depicted herein.

With reference to FIG. 2, the base 22 of the soft tissue anchor 16 maybe flat and generally include a thickness 34 of the before-discussedsheet material. The base 22 may extend in a generally circularconfiguration with a central opening 36 defined therein so as to definea flat ring like structure or the like. With such central opening 36,the base 22 may define an upper surface 38 and an underside surface 40each extending to an inner periphery 42 and an outer periphery 44 of thebase 22. The central opening 36 may be centered axially so as to definea tissue anchor axis 46 (see also FIG. 2A) extending perpendicularrelative to the upper surface 38 and underside surface 40 of the base22. Further, the upper surface 38 and the underside surface 40 mayextend, for the most part, in a planar manner such that the base 22extends as a flat structure. In another embodiment, the upper surface 38and/or the underside surface 40 may be formed with a dome configuration.

In one embodiment, the anchor 16 may include coupling structure 48 sizedand configured to couple the one or more flexible members 20 thereto.Such coupling structure 48 may be formed on or in the base 22 so as tobe associated with the outer periphery 44 or the inner periphery 42 orboth. For example, the base 22 may include the coupling structure 48that may be in the form of multiple extensions or protrusions 50extending outward from the base 22 so as to expand the surface area ofthe upper surface 38 and underside surface 40 of the base 22. Further,for example, the outer periphery 44 may include three protrusions 50such that each protrusion may extend along the outer periphery 44between separate pairs of the multiple legs 24. In another embodiment,the coupling structure 48 may be in the form of notches or recessesformed in the outer periphery or through holes extending between theupper surface 38 and the underside surface 40 of the base 22. In anotherembodiment, the coupling structure 48, similar to that described, mayextend from or be defined in the inner periphery 42 of the base 22. Inanother embodiment, the above-described coupling structure 48 may extendfrom or be defined in both the inner and outer peripheries 42, 44 of thebase 22 or the like. In still another embodiment, one or more of thelegs 24 may act, at least in part, as the coupling structure 48 forcoupling the one or more flexible members 20.

As previously set forth, the soft tissue anchor 16 may include themultiple legs 24 that may extend from the base 22. For example, the softtissue anchor 16 may include six legs or more or less legs. In someapplications, it may only be necessary for the soft tissue anchor 16 toinclude three, four, or five legs. In other applications where theholding strength needs to be greater, the soft tissue anchor 16 mayinclude seven or eight legs. In another embodiment, the multiple legs 24may extend from the outer periphery 44 so as to bend downward. In oneembodiment, the multiple legs 24 may extend in a common direction. Inanother embodiment, the legs 24 may extend downward so as to be orientedto extend generally from the underside surface 40 of the base 22. Inanother embodiment, the legs 24 may extend substantially perpendicularrelative to the underside surface 40 and substantially parallel relativeto the tissue anchor axis 46. In another embodiment, each of the legs 24may extend from the base 22 with a curvature 52 or a radius from theouter periphery 44 to then extend generally linear to a free end 54.With such curvature 52 or radius, the legs 24 may extend downwardrelative to the base 22 such that the free end 54 of the legs 24 may bepositioned with a radial distance 56 relative to the tissue anchor axis46 that may be larger than a radial distance 58 of the outer periphery44 relative to the tissue anchor axis 46. Some portions of the outerperiphery 44, such as ends of the protrusions 50, may extend furtherradially or include a similar radial distance relative to the tissueanchor axis 46 as the radial distance 56 of the legs 24 or free ends 54of the legs. Further, the free end 54 of each leg 24 may extend with afree edge 60 such that an end portion of each leg may extend with atapered portion 62 sized and configured to taper to the free end 54.Such free edge 60 may be defined by the thickness 34 of the sheetmaterial and may be pointed so as to facilitate the legs 24 of theanchor 16 to readily penetrate soft tissue.

Now with reference to FIG. 3, the repair device system 14, in anassembled state, and the components thereof will now be described. Aspreviously set forth, the repair device system 14 may include the softtissue anchor 16 associated with or coupled to the bone anchor 18. Thebone anchor 18 may be sized and configured to be permanently seatedwithin a pre-formed hole (not shown). The bone anchor 18 may be formedof a polymeric material, such as PEEK (polyether ether ketone), or anyother suitable polymeric material. In another embodiment, the boneanchor 18 may be formed of a metallic material, such as titanium, or anyother suitable metallic material or combination of metallic materials,such as stainless steel. In still another embodiment, the bone anchor 18may be formed of a bioresorbable material, such as PLGA(polylactic-co-glycolic acid), or any other suitable bioresorbablematerial. Further, such bone anchor 18 may be formed using typicalmanufacturing processes, as known to one of ordinary skill in the art.

In one embodiment, the bone anchor 18 may be an elongated structure 70to define a bone anchor axis 72, the bone anchor axis 72 extendingaxially and centrally relative to the elongated structure 70. Theelongated structure 70 of the bone anchor 18 may extend between aproximal end 74 and a distal end 76. In one embodiment, the bone anchor18 may be sized and configured with structure to couple to thebefore-described soft tissue anchor 16. In another embodiment, the boneanchor 18 may include bone coupling structure 78 sized and configured tocouple to bone. For example, the bone coupling structure 78 may includemultiple ribs 80 along an outer surface 82 of the bone anchor 18. Themultiple ribs 80 may extend laterally relative to the elongatedstructure 70 of the bone anchor 18. Each of the multiple ribs 80 mayextend continuously around the outer surface 82 of the bone anchor 18such that the ribs 80 may each exhibit a laterally extending arcuatestructure. Further, each of the multiple ribs 80 may be evenly spacedrelative to each other. Further, each rib 80 may each extend to define aproximal rib shelf 84 and a descending tapering side wall 86, taperingdownward from the proximal rib shelf 84, such that the side wall 86 mayextend downward to the proximal rib shelf 84 of a distal rib. In anotherembodiment, the bone coupling structure 78 may include winding threadsextending along the outer surface 82 of the bone anchor 18.

The proximal end 74 of the bone anchor 18 may include a proximal endsurface 88 that may define a generally circular profile. Further, theproximal end surface 88 may define a proximal end hole 90 or recess thatmay receive an engaging structure 142 (FIG. 1) of the deliveryinstrument 12, discussed further herein. Such proximal end hole 90 maybe centrally aligned along the bone anchor axis 72 and within theproximal end surface 88. Further, the proximal end hole 90 may bedefined with a downward or distally extending side wall 92 or sidewalls. In one embodiment, the distally extending side wall 92 mayslightly taper inward toward the bone anchor axis 72 so as to facilitatean interference fit of the engaging structure 142 (FIG. 1) of deliveryinstrument 12 sized and configured to be inserted in the proximal endhole 90. In another embodiment, the engaging structure 142 may slightlytaper toward a distal end 122 of the delivery instrument 12 (see FIG.1).

The distal end 76 or distal end portion of the bone anchor 18 may definea notch 94 or recess therein. Such notch 94 may be sized and configuredto receive a portion of one of the one or more flexible members 20. Thenotch 94 may be an opening extending as a channel in the distal end 76of the bone anchor 18 such that the notch 94 may extend within thedistal end portion of the bone anchor 18 so that a portion of the notch94 extends through opposing sides 96 of the distal end portion of thebone anchor 18. In this manner, the notch 94 adjacent the distal end 76of the bone anchor 18 may receive one of the one or more flexiblemembers 20 to then be pulled deeper within the notch 94 so that theflexible member 20 may extend through and from the opposing sides 96 ofthe notch 94 adjacent the distal end portion of the bone anchor 18.

As previously set forth, the soft tissue anchor 16 may be coupled to thebone anchor 18 with the one or more flexible members 20. The one or moreflexible members 20 may be formed from one or more polymeric filamentsor fibers. The polymeric filaments or fibers may be a polyethylenematerial, such as ultra-high-molecular-weight polyethylene (“UHMWPE”), apolyester material, a polypropylene material, or the like. In anotherembodiment, the one or more flexible members 20 may be formed of suturematerial. In another embodiment, the polymeric filament or fiber may bea bioresorbable material, such as polylactide (“PLA”), polycaprolactone(“PCL”), polydioxanone (“PDX”), or the like, or any other suitablebioresorbable material as known to one of ordinary skill in the art. Inanother embodiment, the filaments or fibers may be formed in a woven orbraided configuration or may extend with strands wound in a side-by-sideconfiguration, or may extend with strands wound side-by-side and in atwisted configuration or any other suitable configuration to form aflexible member.

In one embodiment, the one or more flexible members 20 may include afirst flexible member 98 and a second flexible member 100. The firstflexible member 98 may extend with a continuous loop. The continuousloop of the first flexible member may be sized and configured to extendaround the coupling structure 48 of the base 22, such as the protrusions50, so that the continuous loop wraps around the base 22 of the softtissue anchor 16. The continuous loop of the first flexible member 98may extend with filaments in a braided or woven configuration. Inanother embodiment, the first flexible member may be a flexible wrapmade of one or more flexible filaments that may be wound around thecoupling structure 48 of the base 22, such as the protrusions 50, suchthat the one or more flexible filaments may be wound with multiplewindings.

The second flexible member 100 may extend with a continuous loop. Inanother embodiment, the second flexible member 100 may extend with aloop with two free ends. In another embodiment, the second flexiblemember 100 may be a suture or the like. The second flexible member 100may extend to wrap around and couple to the first flexible member 98adjacent the base 22 of the soft tissue anchor 16. Further, the secondflexible member 100 may couple to the first flexible member 98 atmultiple locations, such as three locations along the first flexiblemember 98. For example, the second flexible member 100 may wrap over andcouple to mid-portions 102 between connection points 104 of the firstflexible member 98 and the protrusions 50 of the base 22 such that thesecond flexible member 100 may pull the mid-portions 102 inward relativeto the base 22 and over the central opening 36 adjacent the innerperiphery 42 of the base 22. From the mid-portions 102 of the firstflexible member 98, the second flexible member 100 may extend downwardthrough the central opening 36 of the soft tissue anchor 16 with adescending flexible member portion that may be in the form of adescending loop portion 106. The descending loop portion 106 may includea lower loop portion 108 that may be coupled to the bone anchor 18. Inone embodiment, the lower loop portion 108 of the descending loopportion 106 may be inserted into the notch 94 defined in the bone anchor18 to couple the soft tissue anchor 16 to the bone anchor 18, aspreviously described. The descending loop portion 106, descending fromthe first flexible member 98, may extend downward with a predeterminedlength 110 so that the bone anchor 18 may be positioned a predetermineddistance from the soft tissue anchor 16. In this manner, the repairdevice system 14 may be assembled with the one or more flexible members20, such as the first and second flexible members 98, 100, coupling thesoft tissue anchor 16 to the bone anchor 18. Further, in this manner,the soft tissue anchor 16 may maintain a substantially fixed distancefrom the bone anchor 18 upon the one or more flexible members 20 beingpulled taut. Further, the soft tissue anchor 16 may be coupled to thebone anchor 18 with the one or more flexible members 20 such that thetissue anchor axis 46 and the bone anchor axis 72 may be substantiallycoaxial or substantially parallel relative to each other.

With respect to FIG. 3A, another embodiment of a second flexible member112 extending in continuous loop form is provided. In this embodiment,the second flexible member 112 may be coupled to the first flexiblemember 98 and to the soft tissue anchor 16 in a similar mannerpreviously described. The second flexible member 112 in this embodimentmay loop around the mid-portions 102 of the first flexible member 98such that the continuous loop may be passed through itself at one loopend portion 114 to then extend downward with a descending loop portion116 which may be sized and configured to couple to the bone anchor 18(FIG. 3), similar to that previously described.

With the repair device system 14 assembled, as depicted in FIG. 3, theassembled repair device system may be assembled with the deliveryinstrument 12, as depicted in FIG. 4. Now with reference to FIGS. 1, 3,4 and 5, the delivery instrument 12 and assembly with the repair devicesystem 14 will now be described.

The delivery instrument 12 may be an elongated structure extendingbetween a proximal end 120 and a distal end 122 with a longitudinallength 124.

Further, the delivery instrument 12 mayinclude a distal end portion 134, the distal end portion 134 including aclipping portion 136, an alignment portion 138, a distal impact surface140, and engaging structure 142. The clipping portion 136 may be coupledto a distal portion of the impact shaft 132 and may include one or moreclips 144 for suspending the soft tissue anchor 16 adjacent a distalunderside of the clipping portion 136. The alignment portion 138 mayextend distally of the clipping portion 136 with a cylindrical structureand may be a continuous extension of the impact shaft 132. The engagingstructure 142 may extend distally of the alignment portion 138 and, morespecifically, may extend from and distal of the distal impact surface140. The distal impact surface 140 may be defined as a shelf 146extending laterally from the engaging structure 142 and may extendsubstantially perpendicular relative to the delivery instrument axis126. The engaging structure 142 may be cylindrical or the like and maybe sized and configured to mate and correspond with the proximal endhole 90 of the bone anchor 18 so that the distal impact surface 140abuts against the proximal end surface 88 of the bone anchor 18. Withthis arrangement, the distal end portion 134 of the delivery instrument12 may be removably coupled to the repair device system 14, as describedbelow.

With the repair device system 14 assembled, the alignment portion 138 ofthe delivery instrument 12 may be inserted through the central opening36 of the soft tissue anchor 16 to then position the engaging structure142 into the proximal end hole 90 of the bone anchor 18. The one or moreclips 144 may be positioned along the underside surface of the base 22of the soft tissue anchor 16 to suspend the soft tissue anchor 16 belowan underside of the clipping portion 136. In this position, the one ormore flexible members 20 including the descending loop portion 106 maybe placed in a somewhat taut orientation or position. With the repairdevice system 14 coupled to the distal end portion 134 of the deliveryinstrument 12, each of tissue anchor axis 46, the bone anchor axis 72and the delivery instrument axis 126 may be coaxial or substantiallycoaxial relative to each other. Further, with this arrangement, therepair device system 14 may be removably coupled to the distal endportion 134 of the delivery instrument 12 and may be employed to fixatesoft tissue 5 to bone 7.

Now with reference to FIGS. 5 and 6, an embodiment for delivering therepair device system 14 with the delivery instrument 12 will now bedescribed. In preparation to deliver the repair device system 14, aphysician may form a hole 9 in the bone 7 adjacent to the locationdesired for fixating the soft tissue 5. Such hole 9 in the bone 7 may beprepared with a suitably sized awl (not shown) or the like, as known toone of ordinary skill in the art. The depth of the hole 9 may be deeperthan a height or elongated length of the bone anchor 18 and should besized and configured to receive the bone anchor 18 with an interferencefit such that the ribs 80 of the bone anchor 18 stabilize andappropriately seat the bone anchor 18 in the bone 7. Once an appropriatehole 9 has been pre-formed in the bone 7, the physician may position aportion of the soft tissue 5 desired for fixating to the bone 7 to aposition over the pre-formed hole 9 in the bone 7. The physician maythen form a thin slit (not shown), such as with a scalpel, within thesoft tissue 5 directly above the pre-formed hole 9 in the bone 7. Thedistal end 76 of the bone anchor 18, being assembled with the deliveryinstrument 12, may then be positioned and inserted through the slit inthe soft tissue 5 so that the distal end 76 is positioned within a topportion 13 of the pre-formed hole 9 in the bone 7. The physician maythen orient the delivery instrument 12 so that the delivery instrument12 may be substantially aligned and coaxial with a central axis 11 ofthe pre-formed hole 9. At this juncture, the physician may employ animpacting instrument, such as a hammer (not shown), to impact theproximal impact surface 128 of the delivery instrument 12. The impactforce of the hammer directly translates to an impact force placed uponthe proximal end surface 88 of the bone anchor 18 abutted with thedistal impact surface 140 of the delivery instrument 12 (see FIGS. 1 and3). As the physician continues to hammer the proximal impact surface 128of the delivery instrument 12, the bone anchor 18 may be driven into thepre-formed hole 9 to a depth desired by the physician. Further, as thebone anchor 18 is driven deeper into the pre-formed hole 9, the legs 24of the soft tissue anchor 16 may simultaneously be driven into the softtissue 5.

Upon the bone anchor 18 being seated or prior to being fully seated, theone or more clips 144 (FIG. 4) holding the soft tissue anchor 16 againstthe clipping portion 136 may be removed. As the physician continues toseat the bone anchor 18 into the pre-formed hole 9 to a depth below anouter surface 15 of the bone 7, the soft tissue 5 becomes clamped with aclamping force 150 against the outer surface 15 of the bone 7 with thesoft tissue anchor 16 being forced downward as the bone anchor 18 isimpacted downward due to the fixed length of the one or more flexiblemembers 20 (and predetermined length 110 (FIG. 3) of the descending loopportion 106), which results in a fixed distance between the bone anchor18 and the soft tissue anchor 16. Due to variableness of the thicknessof soft tissue 5 that may be encountered, the physician may gauge theclamping force 150 or tightness of the soft tissue 5 against the bone 7by continuing to drive the bone anchor 18 into the bone until the softtissue 5 is clamped against the bone 7 with an appropriate clampingforce. In this manner, the repair device system 14 may be employed withvarious thicknesses of soft tissue 5.

Further, the repair device system 14 provides advantages for physiciansby eliminating complex suture patterns necessitated for threading andcinching the soft tissue against bone and implanted bone anchors,whereas the repair device system 14 of the present invention, uponappropriately seating the bone anchor 18 in the bone 7, the soft tissue5 simultaneously becomes fixated to the bone with the soft tissue anchor16. Further, the repair device system 14 minimizes potential issues bybeing implantable in a centralized manner without tangential componentsand sutures being coupled at non-centralized locations, therebyeliminating complexity and potential irritation due to multiplenon-centralized components.

Further, with reference to FIGS. 3 and 6, the coupling of the secondflexible member 100 to the first flexible member 98 facilitates multipleattachment points adjacent the inner periphery 42 of the base 22 of thesoft tissue anchor 16, thereby, more effectively distributing theclamping force 150 across the underside surface 40 of the base 22 of thesoft tissue anchor 16 against the soft tissue 5. Even further, suchdistribution of the clamping force 150 by the coupling of the one ormore flexible members 20 along multiple attachment points around theprotrusions 50 of the base 22 and between the first and second flexiblemembers 98, 100 at the mid portions 102 minimizes the potential forfailure of the first and second flexible members 98, 100. Furthermore,upon the soft tissue 5 becoming loaded laterally relative to the axes46, 72 of the soft tissue anchor 16 and the bone anchor 18, the one ormore flexible members 20 at their multiple attachment points adjacentthe inner periphery 42 of the soft tissue anchor 16 may substantiallyminimize potential overloading due to a spring like effect at theattachment points between the first and second flexible members 98, 100along the mid portions 102, thereby, minimizing potential failure at therepair site and minimizing potential lateral tearing of the legs 24through the soft tissue 5. Also, during the healing process andthereafter, upon the soft tissue 5 becoming loaded by activity of thepatient, the cooperation between the clamping force 150 of the softtissue anchor 16 and the multiple legs 24 being seated within the softtissue 5 may substantially prevent lateral movement of the soft tissue 5relative to the bone 7, thereby, maintaining the soft tissue 5 to becomeproperly fixated to the bone 7 and minimize failure and the potentialfor follow-up procedures. Also, upon fully healing, the only componentsexposed above the soft tissue may be the upper surface of the softtissue anchor 16 and portions of the one or more flexible members 20 toprovide an implant with a very low exposed profile, thereby, minimizingany potential long term irritation to the patient as well as minimizingpotential irritation during the healing process.

Now with reference to FIG. 7, another embodiment of a repair devicesystem 160 is provided. This embodiment of the repair device system 160may include similar structural characteristics and may be employed in asimilar manner as the repair device system 14 of FIG. 3 and described inprevious embodiments. This embodiment of the repair device system 160may include a soft tissue anchor 162 coupled to a bone anchor 164 withone or more flexible members 166. The soft tissue anchor 162 may besimilar to the soft tissue anchor of FIG. 2 and may include a base 168with an upper surface 170 and an underside surface 172 extending betweenan inner periphery 174 and an outer periphery 176. In this embodiment,the base 168 may also include multiple legs 180, such as eight legs,each extending from the outer periphery 176 with a curvature 182 orradius and extending downward relative to the underside surface 172 ofthe base 168. Further, in this embodiment, the outer periphery 176 maynot define the protrusions 50 depicted in FIG. 2 such that couplingstructure may be the base 168 and portions of the legs 180. The boneanchor 164 may include similar structure of the bone anchor 18 describedand depicted in FIG. 3, but in this embodiment, the bone anchor 164 maydefine an aperture 184 extending through an intermediate portion 186 ofthe bone anchor 164 such that the aperture 184 may extend to opposingsides 188 of the bone anchor 164.

Further, in this embodiment, the one or more flexible members 166 mayextend with a single flexible member 190. Such single flexible member190 may extend as a continuous loop or closed loop or may extend withtwo free ends. The single flexible member 190 may be one or moreflexible filaments that may be woven together to form the singleflexible member 190. The single flexible member 190 may be coupled tothe base 168 and coupled against portions of the legs 180 of the softtissue anchor 162. Further, the single flexible member 190 may extendfrom the base 168 and through a central opening 192 defined by the innerperiphery 174 of the soft tissue anchor 162 so as to extend with adownward descending portion 194 to extend through the aperture 184defined in the bone anchor 164. In this manner, the single flexiblemember 190 may be coupled to the bone anchor 164 and the soft tissueanchor 162. With this arrangement, the repair device system 160 may becoupled to bone and soft tissue for fixating the soft tissue to bone,similar to the repair device system 14 described and depicted in FIGS. 5and 6.

Now with reference to FIG. 8, another embodiment of a repair devicesystem 200 that may be employed for fixating soft tissue to bone. Thisembodiment of the repair device system 200 may function similarly andinclude similar structure to the repair device systems depicted inprevious embodiments. For example, the repair device system 200 mayinclude a soft tissue anchor 202 interconnected to a bone anchor 204with one or more flexible members 206. As in previous embodiments, therepair device system 200 may be employed with, for example, the deliveryinstrument 12 of FIG. 5 and may be employed for coupling soft tissue tobone in a similar manner and with similar functionality as depicted anddescribed in FIGS. 5 and 6 herein. Further, as will be apparent to oneof ordinary skill in the art, the repair device system 200 of thisembodiment may be employed with the delivery instrument 250, as depictedin FIG. 12, such that the repair device 200 and delivery instrument 250may be employed with similar functionality for fixating soft tissue tobone as that described and depicted in FIGS. 5 and 6.

With reference to FIGS. 8 and 9, the soft tissue anchor 202 may includea base 208 and multiple legs 210 that each may extend downward or in asubstantially similar or common direction from the base 208. As inprevious embodiments, the base 208 may exhibit a generally circularprofile. The base 208 may exhibit a washer structure with the legs 210or anchoring structure extending therefrom. The base 208 may include anupper surface 212 and an underside surface 214 each extending to anddefining an outer periphery 216 and an inner periphery 218. The innerperiphery 218 may define a central opening 220 or circular opening thatmay be symmetrically defined in the base 208. The legs 210 may extenddirectly from the outer periphery 216 such that the legs 210 may exhibita bend or curve and then extend away from the underside surface 214. Inone embodiment, the legs 210 may be elongated and extend generallyperpendicular relative to the underside surface 214 of the base 208along a majority of the elongated length of the legs. The legs 210 mayextend to a distal end or free end 222 and may be sized and configuredto sink into and engage with soft tissue. In one embodiment, the legs210 may maintain a fixed configuration (pre-delivery and post-deliveryinto soft tissue) that may extend generally linearly, but for theabove-described bend or curved portion of the legs 210 adjacent to theouter periphery 216 of the base 208. In one embodiment, similar toprevious embodiments, the free end 222 or free end portion of the legs210 may exhibit a straight edge profile (side view) and may also exhibita point profile (front view). In another embodiment, each of the legs210 may extend a similar length. The legs 210 of the soft tissue anchor202 may be a length 224 sized and configured to extend with a partialdepth into soft tissue, and not fully through the soft tissue. In oneembodiment, the soft tissue anchor 202 may include six legs 210 or more,such as eight legs. In another embodiment, the soft tissue anchor 202may include four legs, or at least four legs 210. In another embodiment,the soft tissue anchor 202 may include at least three legs 210.

Further, in another embodiment, the base 208 and legs 210 of the softtissue anchor 202 may act as coupling structure for the flexible member206. For example, the flexible member 206 may be coupled to two adjacentlegs 210 as well as portions of the base 208, similar to that describedand depicted in the embodiment of FIG. 7 and discussed in further detailherein. As such, in this embodiment, the outer periphery 216 of the base208 of the soft tissue anchor 202 may extend with a circular profile,but for the legs 210, so as to not exhibit the protrusions as describedin previous embodiments. With this arrangement, the flexible member 206can effectively couple the soft tissue anchor 202 to the bone anchor204.

With reference to FIGS. 8, 10 and 11, the bone anchor 204 of the repairdevice system 200 will now be described. The bone anchor 204, similar toprevious embodiments, may be an elongated structure extending between aproximal end 226 and a distal end 228 and defining a bone anchor axis230 along a longitudinal length 232 of the bone anchor 204. Further, thebone anchor 204 may extend laterally with a circular profile (see FIG.11) and may define ribs 234 extending radially along an external surface236 of the bone anchor 204. Further, similar to previous embodiments,the bone anchor 204 may define a first hole 238 and a second hole 240within the bone anchor 204. The first hole 238 may extend longitudinallyalong the bone anchor axis 230 and be defined in the surface along theproximal end 226 of the bone anchor 204. The second hole 240 may extendlaterally relative to the bone anchor axis 230 and may extend betweenopposing sides of the bone anchor 204 adjacent the distal end 228 of thebone anchor 204 or at a location closer to the distal end 228 than theproximal end 226 of the bone anchor 204.

Regarding FIGS. 10, 11A and 11B, the bone anchor 204 may include aflattened portion 242 or flattened side surface (see FIG. 11). Suchflattened portion 242 may extend along opposing sides of the bone anchorso as to be at least partially defined in the ribs 234 along theexternal surface 236 of the bone anchor 204. Such flattened portion 242may extend from the lateral second hole 240 to the proximal end 226 ofthe bone anchor 204. With such flattened portion 242, the flexiblemember 206 (FIG. 8) may extend through the lateral second hole 240 andextend upward along the opposing flattened portions 242 toward the softtissue anchor 202 (see FIG. 8). With this arrangement, the ribs 234 mayextend radially over the external surface 236 of the bone anchor 204 ina discontinuous manner so as to be separate and discrete relative toother ribs 234. Further, the external surface 236 of the bone anchor 204may exhibit structure along a distal portion 244 of the bone anchor 204to assist the bone anchor 204 to maintain proper orientation andalignment as the bone anchor 204 is implanted into bone. For example,the distal portion 244 of the bone anchor 204 may extend distally fromthe second hole 240 with a cylindrical surface 246 which may transitiondistally to a conical surface 248 so as to taper toward the distal end228 of the bone anchor 204.

Further, as previously set forth, the bone anchor 204 may define thefirst and second holes 238, 240. The first hole 238 may be sized andconfigured to receive an engagement portion 252 of a delivery instrument250 (see FIG. 13A) at the proximal end 226 of the bone anchor 204. Thefirst hole 238 may extend within the bone anchor 204 in a deeper mannerthan depicted in previous embodiments so that the first hole 238 extendsbeyond a majority of the elongated length 232 of the bone anchor 204. Assuch, the first hole 238 may be sized to ensure appropriate engagementand to maintain alignment with the engagement portion 252 of thedelivery instrument 250. The second hole 240 may extend laterallythrough and between opposing sides of the bone anchor 204 adjacent alower end of the opposing flattened portions 242 of the bone anchor 204.Further, the second hole 240 may extend through the bone anchor 204 soas to extend symmetrically through the bone anchor axis 230. The secondhole 240 may exhibit an oval profile, as shown in FIG. 11B, sized andconfigured to receive and hold the flexible member 206 (FIG. 8). In thismanner, portions of the flexible member 206 may extend through thesecond hole in a side-by-side arrangement.

Now with reference to FIGS. 8, 12, 13 and 13A, the repair device system200 may be removably coupled to a delivery instrument 250, similar toprevious embodiments. As in previous embodiments, the soft tissue anchor202 may be maintained in a coupled arrangement to the bone anchor 204with one or more flexible members 206 and, as depicted in thisembodiment, a single flexible member 206. For example, the flexiblemember 206 may extend through the laterally extending second hole 240defined in the bone anchor 204 so that two opposing end loops 256 of theflexible member 206 may extend proximally along the opposing flattenedportions 242 of the bone anchor 204. The end loops 256 may then bepositioned through the central opening 220 of the soft tissue anchor 202so that each end portion of the two end loops 256 may wrap around, forexample, two adjacent legs 210 and portions of the base 208 of the softtissue anchor 202. In this manner, the soft tissue anchor 202 may becoupled to the bone anchor 204 to form the repair device system 200.

Further, the repair device system 200 may be employed to fixate softtissue to bone with the delivery instrument 250, similar to previousembodiments. For example, in this embodiment, the delivery instrument250 may include a handle 258 and a shaft 260, the delivery instrument250 defining a delivery instrument axis 262 extending longitudinallytherein. The handle 258 may define a proximal end surface that may actas a proximal impacting surface 264 (for impacting with a hammer),similar to previous embodiments. The shaft 260 may be fixedly coupled tothe handle 258 and may longitudinally extend distally to a distal endportion 266. The distal end portion 266 may include an alignment portion268, an engagement portion 252, and a distal impacting surface 272. Thealignment portion 268 may be sized and configured to be positionedthrough the central opening 220 of the soft tissue anchor 202. Theengagement portion 252 may be sized and configured to be insertedthrough the first hole 238 defined in the proximal end 226 of the boneanchor 204 so that the distal impacting surface 272 of the deliveryinstrument 250 abuts with the proximal end 226 or proximal surface ofthe bone anchor 204. With this arrangement, the delivery instrument axis262 may be coaxial with the bone anchor axis 230.

In this embodiment, the repair device system 200 may be removablycoupled to the delivery instrument 250 with a retainer element 274. Withthe distal end portion 266 of the delivery instrument 250 engaged withthe bone anchor 204, as previously set forth, the retainer element 274may be sized and configured to hold and suspend the soft tissue anchor202 along the distal end portion 266 of the shaft 260 so that theflexible member 206 is taut or in a taut position. In this tautposition, the soft tissue anchor 202 may be retained at and spaced apredetermined distance from the bone anchor 204 so as to be suspendedabove the bone anchor 204. The retainer element 274 may include a line276 and a tab 278. As depicted in FIG. 13A, the line 276 may extendalong the underside surface 214 of the base 208 of the soft tissueanchor 202 and extend upward on both sides of the base 208 to the tab278. The tab 278 may define channels 280 therein or coupling structurefor holding portions of the line 276. The tab 278 may also be sized tocouple to the shaft 260 of the delivery instrument 250 with, forexample, an interference fit or the like such that the line can bewrapped around the shaft 260 so as to assist in the interference fit. Inthis manner, the retainer element 274 may maintain the flexible member206 in a taut position so as to temporarily and removably hold or couplethe repair device system 200 to the delivery instrument 250 and, uponfixating soft tissue to bone with the repair device system 200, the line276 may be removed by, for example, being snipped and then pulled fromunder the soft tissue anchor 202. In another embodiment, the tab 278 ofthe retainer element 274 may be removed from the shaft 260 to facilitatereleasing the wrapped line 276 held between the tab 278 and the shaft260 to, thereby, release the delivery instrument 250 from the repairdevice system 200.
